Pluto has a shape that is nearly round, and it orbits the Sun. It has five known moons. It is called a dwarf planet and not a planet because its orbit is not cleared of like-sized or larger objects
Answer: Option B
<u>Explanation:</u>
According to the International Astronomical Union (IAU), Pluto has been mentioned as Dwarf Planet as it doesn't hold the standardisation to be counted as a Planet.
According to the standard criteria, a planet must have been surrounded by the orbit of the Sun, it must have significant mass to have a gravitational pull and hence, circular shape, and should have isolated surrounding.
But, Pluto has various celestial bodies in its vicinity that are larger in size. Hence, as concluded by the Union, any celestial body that does not has clear surrounding, is regarded as Dwarf Planet just like Pluto.
Answer:
the gravity was pulling the cup to the front of the window even though the wind was pushing it the other way.
Explanation: the gravity must be strong
2.1 kg of sodium bicarbonate is equal to the 2.1 x 10¹² ng of sample. Option D is correct.
Mass is the quantity of the substance in the body or object. The SI unit of mass is Kilogram.
There are other units of measure,
- Milligram: 1 g is equal to the
- Micro-gram: 1 g is equal to
- Nano-gram: 1 g is is equal to
First convert kg to gram,
Since, 1 Kg = 1000 g
2.1 kg = grams of sample
So,
Do the cross multiplication,
Now, convert 2100 g to nano-grams
Since, 1 g = 1 x 10⁹ ng
2100 g = ng of sample
So,
Do the cross multiplication,
Therefore, 2.1 kg of sodium bicarbonate is equal to the 2.1 x 10¹² ng of sample.

Because its a vacuum, there's no air resistance, they will fall at same time
Applying gravity acceleration rule g=9.8m/s which is taken as 10m/s sometimes.
